Abstract

A power generation plant (1) comprises a boiler (3) including an economizer (18) and a superheater (13), a steam turbine (5) driven by steam generated in the boiler (3), a generator (37) driven by the steam turbine (5), a feed water heating boiler (7) for heating feed water fed to the boiler (3), and a feed water heating thermal exchanger (60) thermally exchanging steam generated in the feed water heating boiler (7) with the feed water to be fed to the boiler (3), and a control section (30) controlling heating quantity of feed water according to the feed water heating boiler (7).
